UNITED STATES PATENTb OIIIcn DARIUS WELLINGTON, OF BOSTON, MASSACHUSETTS.

Specification forming part of Letters Patent No. 125,363, dated April 2, 1872; antedated March 30, 1872.

To all whom t may concern:

Be it known that I, Dhnrus WELLINGTON,

. of Boston, in the county of Suiiolk and State self-close them when released or after having been'opened by hand,`the improvement being upon that class of valves which are opened and closed by rotation of a valve spindle. The invention consists in making the valvespindle with a pinion-gear, into which mesh gear-teeth made on the pivoted end of a weight or lever hung upon a suitable stud. When the spindle is turned to openv the valve the pinion teeth actuate the lever and lift its weighted end, and when the spindle is released the gear-teeth of the lever operate the pinion, rotating the spindle and closing the valve. It is in a self-closing valve operated by a weight having gearfteeth meshing into a pinion on the valve-spindle that the invention consists.

The drawing represents in sectional elevation a valve embodying my improvement, showing in full lines the valve closed, and in dotted lines the valve open.

a denotes the body of the cock; l), the valvechamber5 c, the valve; d, the induction-tube 5 c, the educlion-tube; f, the valve-seat 5 g, the valveoperating stem or spindle, the spindle rotating in suitable bearin gs, and having a nuttliread, la, on its lower end, into which works the screw-thread of a shank, la, extending from the valve, rotative movement of the spindle effecting the upward movement of the valve to open the water-passage through it, or the downward movement of the valve to close said passage, in accordance with the direction of such rotative movement. Oast upon or fixed to the spindle is a gear-pinion, Z, meshing into the teeth of which are gear-teeth, m, on a plate, n, hun g upon a stud-pin, o, and having a weight or weighted arm or projection, p, as seen in the drawing.

When the spindle is turned to open the valve, the pinion lifts the weight, as seen by the dotted lines, and when the hand is removed irom the spindle the weight falls by gravity, and, in falling, turns the spindle and closes the valve, as seen in the drawing'.

This construction is valuable for other watersupply cocks or valves than those intended for water-closets, or for such cocks, faucets, or valves as are intended to be self-closin g to prevent waste or overflow of water, and which are to be open while, and only while, the party drawing water holds the spindle, the weight being, in many cases, for such purpose an iinprovement upon a spring for operating the valve.

I claim- A compression-cock in which the valve is directly raised from its seat by turning the handle of spindle g, and is thrown to upon its seat by a pinion, l, on the spindle, being rotated by the weighted gear-plate mthe spindle having a nut-thread, h, into which the screwthread t' of valve-stem la works, substantially as shown and described.
